FLANGlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 411,780, dated October1, 1889.

Application filed June 19, 1888. $erial No. 277,546. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN R. BROWNELL, a citizen of the United States,and a resident of the city of Dayton, in the county of Montgomery andState of Ohio, have invented certain new and useful Improvements inFlanging-Machines, of which the following is a specification.

The several features of my. invention and the advantages arising fromtheir use, conjointly or otherwise, will be apparent from the followingdescription.

Myinvention relates in general to machines for forming flanges at or outof the edge of holes in metal plates, and is more particularly intendedfor forming such flanges upon boiler-heads.

The particular portion of such a Hangingmachine, to which my improvementmore particularly relates, is what is known as the flanging-head.

My invention is applicable to various descriptions of fianging-machines;but for the purposes of illustrating the application and operation of myimprovement I have shown it inconnection with one of the common andwell-known descriptions of flanging-machines.

In the accompanying drawings, forming part of this specification, Figure1 is a side elevation of a drill-press or flangingmachine adapted foruse with my improved fianginghead. Fig.2 is a side elevation of my im-'proved hanging-head. Fig. 3 illustrates a convenient form of clutch forenabling the main vertical operating-shaft to engage in thefianging-head and to rotate the latter. Fig. 4 is a view of thefianging-head in position in the machine and of -the sheet beingflanged, the said figure being partly in vertical section and partly inelevation. Fig. 5 is aview of the under surface of the fianging-head.Fig. 6 is a top view of the hanging-head. Fig. 7 is a section taken atthe line y y, Fig. 5. Fig. 8 is a section taken at the line .2 2, Fig.5. Fig. 9 is a central section of one of the vertical rollers (that isto say, whose axis of revolution is horizontal) of the flanging-head.Fig. 10 isa central section of one of the horizontal rollers (that is tosay, whose axis of revolution is vertical.) of the hanging-head. Fig. 11illustrates the shape and position of 'or welded in one piece.

the metal sheet to be flanged as the lower or first roll is operatingupon it. Fig. 12 illustrates the shape and position of the same sheet asthe upper or finishing roll is acting upon it, while the lower or firstroller is acting upon the lower portion of the flange. In these views(Figs. 11 and 12) the rollers are shown in elevation, while the sheet tobe flanged and the upper edge of the cylinder F, or equivalent support,are shown in section, and for the purpose of better illustrating theoperation of the upper and lower series the lower or horizontal roll isshown apparently directly beneath the vertical roll E.

The frame of the Hanging-head consists of a hollow central stem A, abase portion or plate B, and a series of heavy radial lugs O, the stem,plate, and lugs being preferably cast The beveled flanges 1) projectdown from the plate B and serve as guides, first entering the opening inthe plate to be flanged. For the purposes of perspicuity it may be hereremarked that each of these rolls or rollers which rotate around ahorizontal axis or around an axis extending in a directionsubstantiallyhorizontal is termed a horizontal roll or roller, and thateach of those rolls or rollers which rotate around a vertical axis oraround an axis extending in a direction substantially vertical is termeda vertical roll or roller. A series of horizontal rolls D is attached tothe plate B in the spaces between the lugs O. Each roll is mounted onthe end of an arm D, to which it may be attached in any desired manner,the preferred means being a disk d, countersunlcin the face of theroller, and a screw 61', passing through the disk into the arm D. Thearms D rest on the top of the plate B, and their inner ends are, for thepurpose of being more efficiently braced, preferably received inrecesses in the stem A. They are held in place by plates (1 which areclamped down onto the arms by the bolts and nuts (1 one on either sideof each arm. The rollers D thus held in place are capable of a certainamount of adjustment to and from the center, stem.

By reference to Fig. 5 it will be seen that the axes of the rollers D donot correspond exactly with the radii of the plate B, but run parallelto the radius and in advance of the center of the flanging-head. Thisarrangement tends to prevent the arms holding the rollers from beingdragged out of place, and also tends to prevent such a pressure upon therollers as would tend to drag them off their respective shafts or armson which they (the rollers) respectively revolve. Being set ahead, theyperform their work ahead; hence the metal which is being flanged doesnot crowd onto them.

The vertical rollers E are mounted on the stems or axes 6, preferablysecured to the head by a screw-thread, as shown. (See Fig. 7.) Thesestems e are preferably attached to the horizontal arms 6 of theangleirons e, thereby securing the vertical rollers to said angle-irons.These angle-irons e are secured to "the lugs C by screws a passingthrough their vertical arms 6 As shown in Fig. 5, the angle-irons e areattached to the sides of the lugs O, and their lower horizontal arms 0,with the rollers E, are received in recesses cut in the bottoms of thelugs C, as shown in Fig. 7. This arrangement distributes the strain sothat verylittle of it is brought to bear on the screws 6 and 6 Whendesired, the lugs C may be provided with the guide-flanges 0. (Shown inFig. 6.) The vertical rollers E preferably project horizontally beyondthe horizontal rollers D, and the bottoms of the horizontal rollers Dare lower than the bottoms of the vertical rollers E. The lower orhorizontal rollers D are not quite so much beveling or rounded as arethe upper or vertical rollers E. In other words, the vertical rollers Epreferably have a little more bevel than the lower or horizontal rollersD. The object of thus beveling the vertical rollers E is that they shallnot strike the sheet so abruptly as they otherwise would do. The lowerend of the stem A has a central opening screw-threaded interiorlyfor-engaging the screw-thread of the screw G. The upper end of the stemA is provided with the clutch-teeth Y, to engage with the clutch A inthe end of the rotating shaft H of the press or machine proper.

Immediatelyunder the rotating arm of the press a cylinder F, of the sizeof the flange to be made,is secured, and through it, centrally located,a screw G projects upwardly and is securely fastened to the bed-platebelow. In flanging a plate it is placed on the cylinder so that thecenter of the opening to be flanged corresponds with the center of thecylinder. The fianging-head is now screwed onto and by means of thescrew G down onto the plate, the flanges 12 passing through the openingtherein and the rollers D resting on the plate. Power is now appliedthrough the medium of the press, the shaft'II is so rotated, and theflanging-head screwed down, forming a flange on the plate as itsdescends. In this operation the'horizontal rollers first turn or breakdown the flange, and the vertical rollers finish the opening of propersize and impart a finish. to the inner surface of the flange orboiler-head and of the opening in the sheet. The head keeps onbevelinguntil the head of the rollers or rolls passes clear through thenozzlethat is, through the flanged opening in the boiler-head or otherpiece of metal.

The general construction of the machine illustrated to operate myimproved flanginghead is as follows, viz:

K is a suitable frame, one portion of which supports in a suitablejournal-bearing the shaft N, carrying the tight and loose pulleys I andI, and also the pinion P, fixed to said shaft. This pinion P meshes withthe gearwheel 0, fixed on shaft Q, the latter be ing suitably supportedin journal-bearings Q Q, in said frame and carrying a bevel-- pinion R,fixed to said shaft Q. This pinion R engages with bevel-gear S, splinedto shaft H. This shaft H is journaled in the bearing H, and is alsojournaled in the bearing H substantially as shown. The lower end ofshaft H is provided with a head Z, which has a rectangular hole, intowhich the square end of the upper half of the clutch is I inserted andheld.

The shaft II is capable of vertical movement, and such movement isimparted to it and controlled by the operator through the agency of thelever J, fulcrumed in support M of the frame K and provided at its upperend with link j, the latter being pivoted at one end to lever J and atits other end to the head 71, whose lower end 7c is inserted in theupper end of shaft H and allows the shaft H to rotate around it andyetprevents the shaft from slipping off from it. This describes all ofthe mechanism necessary to operate the fianging'head.

In operation, the flan gin g-head being placed as aforementioned uponthe boiler-head or other metal to be flanged, the lever J is operated todepress the shaft H and its clutch Y. The latter in descending engagesthe clutch Y upon the hanging-head, power being communicated to thetight pulley I, the shaft H rotates the flanging-head, and by means ofthe screw G screws down the flanging-head and flanges the metal, asaforementioned. The hand-wheel T, with sleeve 25, and the collar lV,withits screw IV for setting it on the shaft H, all have to do with usingthe same machine as a drill-press in place of a flanging-machine, and astheir construction and mode of operation are well known and as they areunnecessary to the operation of my invention further mention of them isomitted. The clutch Y may be omitted and other means of connecting theflanging-head to mechanism for rotating it may be employed. So also thescrew G may be omitted and other means be employed to guide and steadilyforce the flanging-head through the opening in the boiler-head or othermetal. I

WVhile the various features of my invention are preferably employedtogether, one or more of said features may be employed without theremainder, and in so far as applicable one or more of said features maybe used in connection with flanging devices other than those hereinspecifically specified.
